-2sin(θ)=sqrt(2)

- 2 sin (θ) = 2

θ = \frac{5 π}{4} + 2 πn, θ = \frac{7 π}{4} + 2 πn

Degrees

θ = 22 5^{\circ} + 36 0^{\circ} n, θ = 31 5^{\circ} + 36 0^{\circ} n

Solution steps

- 2 sin (θ) = 2

Divide both sides by

- 2

- 2 sin (θ) = 2

Divide both sides by

- 2

\frac{- 2 sin ( θ )}{- 2} = \frac{2}{- 2}

Simplify

sin (θ) = - \frac{2}{2}

sin (θ) = - \frac{2}{2}

θ = \frac{5 π}{4} + 2 πn, θ = \frac{7 π}{4} + 2 πn

θ = \frac{5 π}{4} + 2 πn, θ = \frac{7 π}{4} + 2 πn

tan (2 x - \frac{π}{6}) = \frac{1}{3 ^{\frac{1}{2}}}

sin^{2} (\frac{x}{2}) - 1 = 0

69 = cos (x)

sin^{2} (θ) = cos (θ) + cos^{2} (θ)

7 cos (θ) = 2 + 9 cos (θ)
